The hormone cortisol is a very important hormone for regular function in humans and many other animals. Cortisol is a steroid hormone (a derivative of cholesterol).1 It is produced in the adrenal glands of the kidneys2 and is especially important when an individual faces a stressor.3 Unusually high or low concentrations of cortisol will almost certainly have an adverse effect on regular human function.

It is now well established that the brain and the gut are engaged in constant bi-directional communication. Most individuals are made aware of such communication when alteration in gastrointestinal function is communicated to the brain bringing about the perception of visceral events such as nausea, satiety, and pain or when, in turn, stressful experiences lead to altered gastrointestinal secretions and motility. The mechanisms which allow communication between the central nervous system (CNS)…

The Endocrine System controls bodily functions that tend to occur over a long time. Taking a similar role to the nervous system to keep the body in a state of homeostasis. Through the use of a negative feedback loop the Endocrine system insures the proper amount of hormone is in the body at any given time. These hormones serve functions from growth to balancing ion levels in the body. The Endocrine system is specifically down to the hormone meant for homeostasis. The Endocrine System is…

Lying within the core of the human brain is a small gland known as the pineal gland which is the principal conductor and regulator of the endocrine system. Furthermore, another essential process that the pineal gland undergoes is the secretion of melatonin, an autacoid hormone that controls the body’s circadian rhythm. Aside from controlling the body’s natural circadian rhythm, melatonin is used to cure many different conditions including radiation exposure, Alzheimer’s disease, and tinnitus.…

The sexual development and function of the body and the metabolism are two examples of what the endocrine systems does. The major contributors to the endocrine system include the pituitary gland, thyroid, hypothalamus, parathyroid, adrenal glands, pineal body, reproductive glands, and the pancreas.

Growth stimulants are usually given to nursing calves which will give the calves a higher weaning weight by five to fifteen percent. The common growth stimulants used are Ralgro (zeranol, synovex C, and compudose which are implanted under the skin of the ear in a pellet. The pellets will not stay under the skin they will dissolve over a period of time which supplies the growth stimulant to the bloodstream. There was been was studies that have shown that he use some implants and the repeated…

Epidermis is the tough outermost layer of the skin, and is made up of the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. It is mainly comprised of the protein keratin, squamous epithelial cells and melanin. The epidermis acts as a waterproof barrier and the melanin absorbs ultra violet light to prevent burns, inflammation, and swelling of the skin. Dermis is the lower layer of the skin that contains collagen, nerve fibers, lymph vessels, and blood…
